OBJECTIVE
The determinants that promote living beyond life expectancy and successful aging still remain unknown. The aim of the present work was to evaluate the role of energy balance in successful aging, in a random sample of older adults living in the Mediterranean basin.
METHOD
During 2005 to 2011, 2,663 older (aged 65-100 years) adults from 21 Mediterranean islands and the rural Mani region (Peloponnesus) of Greece were voluntarily enrolled in the study. Dietary habits, energy intake, expenditure, and energy balance were derived throughout standard procedures. A successful aging index (range = 0-10) was used.
RESULTS
After adjusting for several confounders, high energy intake (i.e., >1,700 kcal/day), b-coefficient [95% CI] = -0.21[-0.37, -0.05], as well as positive energy balance, b-coefficient [95% CI] = -0.21 [-0.37, -0.05], were inversely associated with successful aging.
CONCLUSION
A diet with excessive energy intake and a positive energy balance seems to be associated with lower quality of life, as measured through successful aging.
目的
促进超出预期寿命生存和成功老龄化的决定因素仍然未知。本研究的目的是在居住在地中海盆地的老年人随机样本中，评估能量平衡在成功老龄化中的作用。
方法
在2005年至2011年期间，来自21个地中海岛屿和希腊伯罗奔尼撒半岛农村马尼地区的2663名年龄在65至100岁之间的老年人自愿参加了该研究。通过标准程序得出饮食习惯、能量摄入、支出和能量平衡情况。使用了一个成功老龄化指数（范围=0至10）。
结果
在对多个混杂因素进行调整后，高能量摄入（即>1700千卡/天），β系数[95%置信区间]= -0.21[-0.37，-0.05]，以及正能量平衡，β系数[95%置信区间]= -0.21[-0.37，-0.05]，均与成功老龄化呈负相关。
结论
通过成功老龄化衡量，能量摄入过多和正能量平衡的饮食似乎与较低的生活质量相关。
